Abstract

The invention relates to a power distribution cabinet with compact structure and simple wiring. A plurality of circuit breakers are installed in the power distribution cabinet. A plurality of displayports are formed in one side of the power distribution cabinet, and an interaction module is installed in a display port of the power distribution cabinet. An electrical parameter acquisition device,an actuating mechanism and a control circuit are arranged in the circuit breaker; and the electrical parameter acquisition device is installed on a busbar of a three-phase main loop in the circuit breaker. The executing mechanism is used for controlling the working state of the circuit breaker, and the control circuit comprises a main control chip and a communication chip. Traditional voltmeters,ampere meters, multifunctional meters, voltage transformers, current transformers, indicating lamps, buttons and the like are replaced. Secondary circuits in the power distribution cabinet and the power distribution box are greatly simplified, the material cost, the labor cost and the maintenance cost are greatly reduced, and the economic benefit is considerable.

Description

Technical field [0001] The invention relates to the field of electrical systems, in particular to a power distribution cabinet with a compact structure and simple wiring. Background technique [0002] In the prior art, there are mainly two types of power distribution cabinets: [0003] The economical power distribution cabinet is equipped with traditional pointer current and voltmeters, which cannot display complete three-phase current and three-phase voltage. It only displays one-phase voltage and three-phase current, or even only one-phase voltage and one-phase current. . The circuit breaker only has the function of manual opening and closing. Since the circuit breaker runs in the power grid, manual opening and closing may increase the operator's risk. [0004] The high-end power distribution cabinet is equipped with a multi-function meter, which can flip the screen to display a variety of rich information such as three-phase voltage, three-phase current, power, and electric ener...
